AN INVESTIGATION OF SOLAR INDUCED PHENOMENA AT MAGNETICALLY CONJUGATE POINTS, PART I (CHAPTERS I-III).

Abstract

The results of a comprehensive study of a solar induced geophysical phenomena at pairs of stations linked by a magnetic field line are presented. Studies have established that magnetic variations (except S sub q), telluric currents, ionospheric absorption, visual auroras, VLF and ELF emissions and auroral X-rays occur in similar manner in conjugate areas-- in time, form and amplitude. The variations of the magnetic field were the most thoroughly studied phenomena. It was found that auroral zone electrojets occur in conjugate patterns, and that a conjugate area, elongated in geomagnetic latitude, can be defined by comparisons of magnetic records. This conjugate area appears to move in time, as the electrojets depart somewhat from conjugate patterns. The magnetic variations at mid and low latitude due to the return current paths of the electrojets are conjugate to approximately the same degree as the 'primary' auroral zone activity. At very high latitudes there is a diurnal variation in the degree of correlation at conjugate points--probably due to the distortion of the magnetic field by the solar wind. (Author)
